tool or die holder so that various tools o1'y dies may be used in the machine to produce various types of shingles or shingle strips.

Another object is to provide improved means for holding the tools from spreading during the cutting or forming operations.

With these and incidental objects in View,

the invention consists of certain novel fea` tures of construction and combination of parts, the essential elements of which are hereinafter described with reference to the drawings which accompany and form a part of this specification. Y In the drawing, Figure 1 is a section taken on the line 1 1, Figure 2; Figure 2 is a section taken on the line 2 2, Figure 1 with the chains and part of the bars removed; Figures 3 and 1 are partial sectional ,details on the line 3 3, Figure 2, showing the cam operation of the machine; Figure 5 is @fragmentary view of some of the .transverse bars of the machine showing slots and apertures for receiving dies and knives; Figure 6 is a similar view showing one type` of knife inserted in the bars; Figure..7 is a similar view showing a second type of knife inserted in the bars; Figure 8 is a similar view showing one type of punch carried by one of the bars; Figure y9 is a section taken on the line 9 9, Figure 8; Figure 10 is a section taken on the line 10 10, Figure 8; Figure 11 isa section taken on the line 11 11, 'Figure 6; Figure 12 is a plan view of one of the bars of a second type of die; Figure 13 is a section taken on the line 13 13, Figure 12; Figure 14: is a section taken on the `line lll-14, lFigure 12; Figure 15 is a plan view of a shingle strip made by the dies shown in Figure 12; Figure 16 is a fra mentary plan view of a rooflaid with ythe s ingles of this type; Figure'l? is'a plan view of a shingle strip made by the knife shown in Figure' 6; Figure 18 is a fragmentary plan view of a roof laid with shingles of this type; Fi ure 19 isa plan view of a shingle strip rnae from dies shown in Figure 8; Figure 20 is a fragmentary plan View of a roof laid with shingle strips of this style; Figure 21 isa plan view of a shingle strip made from the knives shown in Figure 7 Figure 22'is` a fragmentary plan view of a roof laid with shingle strips of this type; Figure 23 isa plan view of a strip showing how two shingle strips of the type shown in Figure 19 are formed with one punching operation; Figure 24 is a similar view of a strip from which the shingle strips of the type shown in Figure 15 are made; Figurev y25 is a. similar view showing the stri l from which the shingle strips'shown in igure 21 are obtained; and Figure 26`is a similar view of a strip showing the manner in which` the shingle strip shown in Figure 17` is cut out.

|The machine shown and deseribedherein y is something of the general type of that shown in my co-pending application Serial Number 329,874, filed October 10, 1919,r but important improvements are incorporated herein and only the' novel features and improvements willbe claimed.

The chains 1 and 2, Figure l, carry `transeoy versebars 3 and 4, respectively, which I prefer'to'make wider than of the type shown in my co-pending application aforesaid, so each one of the bars carries a tool.

In my present machine I have so designed' 90 these bars and the cams for actuating them that with a single set of bars, I can, by changing the tools in the bars, makeshingle strips of various styles, including several types wherein the edges of the formed shingles are cut by knives and in Asuch fashion that two adjacent shingle strips will nest, one with thefother, and can also form several styles of shingle strips whereinl the tabs are formed'by punching material from f 100 the sheet instead of merely` cutting the material.`

Looking at the bars 11,` as shown in Figure 5, it will be seen that each of the bars has a longitudinal groove 5 therein 'in 105 which may be inserted a cutting 0E knife to cut the sheet of material at theend of each successive shingle strip.

In the bar 4 is also a diagonal groove 6 `which inthe succeeding bar is positioned in Y 1 must provided for creating' a considerable .that ne ii and 25, Figure l needing o r nre 7, so formed as to out shovvn [gifle fashion nnen root niesent the appeareiztensions end carry a punei liny l 1 punch v ey strips oit the style shown in Figure 'lo will be formed7 whichu when superimposed t putting; operation,

diagonally opposite direction. These grooves are to carry knives such as 7, n igure G, and to cut a strip of ineterial as shown in Figure 265 so as to 'oi'in tivo shingle strips ot the style shown in ll'gure l?, which? when superimposed shingle fashionupon a root', presents the .ippearance oli' style sho-mi in Figure l The bar l also has eonnectins 9, and Wj which are reversed and which earrv knives 'l striof the Istyle shown iii thereby tivo sini s i n'll`igure /llS which villen placed shin-- ire ot h und die,

Althoiigh the cutting operations per-- formed by the knives described be ae ooniplishod any place between vertieal planes passing; through tie points 22 and ,fl-23, Figure l, l prefer to perform this cutting` operation at the pointQfZ, as indicated vin Figure l.

For this purpose l prefer to use 'rollers between which the bars are squeezed during; the (uniting` operation, it being` understood that the apertures in the upper bars provided as 'tenisle members of the dies are plugged in the bars during the ong; the ends rlhe severing` 'of the strips al w 197 end 2Ll is accomps such as shown in liliggures lli: and i9, may also be user to torni shingle strips oit the. kind shou'i. in my Patent tt-1,207,523, issued lleceinber 5, ll, and
